Internet Accounts will not let me add my Facebook account
I just upgraded to High Sierra and I have several problems (always occurs after an update), but one that is really frustrating me is that I have been trying to add my Facebook account for use with iCal, but I cannot get it to accept my user name or password. The message I get is "unable to verify account name or password". I am using the same password on my iPad and iPhone with no problems. I have tried various account names (email, user name, full website link), deleted all KeyChain passwords. Nothing is working! I noticed that several people have had the same problem in the past, but no one has seemed to come up with a solution. So, I am opening this up again for another try.
